[QUOTE="pods8, post: 1057551, member: 83233"] Right/wrong here's what I've done when dealing with 100yd ranges to do most initial work at: Load up .5gr incremental singles and shoot them over a chrono while comparing velocity/bolt lift/primers and reviewing against any published data for that combo to get an idea of what a max charge may be for the components I have in hand. Then depening on case capacity I'll load up incremental singles in .1gr or .2gr steps so I cover the upper portion of the charge range (but below the max). I'll put up a few targets that all have 3 aim points per sheet, and I'll shoot 3 shots per aimpoint (that's a good amount that I can keep track of each individual hit). I'll log the velocity and location. Then at home I'll compare the hits/velocity of things (superimpose them between aimpoints as needed) and look for the adjoining powder charges that gave the tightest combinations. Assuming a few in there I'll load up 3 or 5 shot groups of those and try those out. Ideally something shows promise from that and then you evaluate at longer distances and try to tweak seating depth, etc. That's worked for me in the sub 400yd stuff. [/QUOTE]
